I've tried Bitwarden for a few days with their Firefox plug-in. During those few days there were multiple occasions were it would create a password for me, but wouldn't save the login.
I switched to 1password and it is way better in letting you know if it saved a password or not. I also ran in to some other small issues with the Bitwarden ux that made it less than ideal to use.
I want to like Bitwarden, but 1password just seems to be better at managing passwords.
